Facebook & Google Conversion Tracking Not Working

Is anyone experiencing issues with their Facebook Pixel and Google’s enhanced conversions pixel not tracking conversion events properly? Both pixels are set up properly in our store and are recording some events (add to cart, reach checkout, etc.), however, both pixels are not recording checkouts. This started on August 31st when Shopify started to experience issues with Google Tags and customers not being able to reach checkout.

Any feedback on how to fix this would be much appreciated!
